GONNEGTER- FOR SASH AND SASH CORD.

Application filed April 11, 1923, Serial No. 631,417. Renewed March 26, 1927.

In metal windows sash cord connectcrs have been found impractical, for thereason that they constantly break when connecting and disconnecting the sash cord which is in the form of a chain.

With the character of connecters heretot'ore used it is necessary .to bend the connecter (which is in the form of a hook) to attach and detach the sash cord.

Therefore, the invention has for its purpose the provision of reversely disposed hook ears arranged in parallelism and adjacent each other, whereby upon slightly springing apart the hook ears and inserting 5 a link of the sash chain or cord between the ears, and imparting a turn or twist to the link, the link may engage both hooks of the ears simultaneously. It has been found that this construction does not cause the ears to break as readily as in the old method of attaching sash cords, hence affording a practical connecter.

Another purpose is the provision of simple and improved means for attaching the hook ears to the sheet metal sash.

Still another purpose is to provide a sheet metal sash rail especially adapted for use in conjunction with connecters or" this character.

A further purpose is to provide a sheet metal sash rail includingsimple and improved means for glazing and retaining the glass in the rail.

It is to be understood that the particulars herein given are in no way limitative and that While still keeping within the scope of the invention, any desired modificationsof detail and desired proportions may be made in the device according to circumstances.

The invention comprises further features and combinations of parts, as will be hereinafter set forth, shown in the drawings, and claimed.

In the drawings v Figure 1 is a perspective view of a portion of a sheet metal sash, showing its construction, and also the improved connecter as applied;

Fig. 2 is a sectional view Fig. 1;

Fig. 3 discloses perspective views of both hooked ears, which constitute the connecter as a whole;

Fig. 4 is a detail sectional view 01 a modified form of sheet metal sash, wherein a wood or other filler is used, and showing on line 22 of a modified construction of fastening the hooked ears to the sash; and

Fig. 5 is a sectional view on line 55 of Fig. 4. i v

Referring to the drawings, 1 designates a sash rail. It is well known that four rails are necessary to form the sash, and therefore the adjacent ends of the. rails are mitered and fastened "together by any suitable means, such as spot welding or the like, as at 2. 1 I

The horizontal rail of the sash at each end is provided with an elongated transversely disposed slot However, this slot 3 may be arranged longitudinally of the rail, in

case it is desired to dispose the ears of the v connecter, at, right angles to that shown in Fig. 1.

The connecter comprises a pair of sheet metal ears 42 The ears when applied to the sash are arranged in parallelism and ad' jacent each other, as shown in Fig. l. The lower ends of the ears are inserted through the slot 8 and are bent as me. The bent portions 6 may be secured to the inner surface of the wall of the sheet metal. sash rail by any suitable means, preferably spot welding, as indicated at 7, Figs. 2 and 3.

In constructing or stamping the ears, they are formed with openings 8' which,

when the ears are placed in parallelism and in contact with each other, register for the purpose of receiving an end link 9 of the chain or. sash cord, not shown. The ears are also formed with slots 10 arranged on angles, as shown in Fig. 1, and merge into the openings 8. It will be noted that the cars are so disposed that the slots 10 are reversely disposed, so that the diametrically opposite portions of the bodies of both ears will close the slots 10 when the ears are in contact.

However, when the ears are sprung slight- 1y apart, sufliciently to receive the link between them, substantially a quarterturn or twist may be imparted to the link, causing opposite portions of the link to engage the slots 10, and when tension is applied to the link 9 its lower portion will engage with the openings 8, as shown in Fig. 1.

It has been found that connecting ears of this character will not break as readily as 'will the attaching hooks or other connecters,

from the openings 8 hooks 11 are caused to be formed. These hooks extend in opposite directions toward the sash rail, and as long as the sash cord or chain is under tension, 1t 1s imposslble tor the chain or cord to accidentally disconnect jlirou'i the connecter.

The sash rail is hollow and constructed of any suitable sheet metal, iireferably galvair ized iron.

The inner portion of the wall of the rail is -formed with a channel 12, and one of the side walls 13 of the channel adjacent the bottom thereof is formed with a lateral tongue 1 extending longitudinally of the channel. This tongue 14 constituted a seat for the glass 15.

The channel 12 adjacent its bottom is also formed with a recess 16 extending longitudinally of the channel adjacent the tongue 1d. The opposite wall of the channel has a flange 17, which is formed by bending the wall of the metal.

A hollow retaining bead 18 is designed to engage with the channel, it being necessary to spring the opposite sides of the bead into position. The head 18 has a flange 19 which contacts with the flange 17. The opposite wail of the bead has a longitudinal lateral flange 20, which engages the recess 16. In order to permit the flange 20 to engage the recess 16, it is necessary to press the opposite sides of the head toward each other, and atter the bead is in proper position, pressure upon the opposite sides thereof is relieved, allowing the flange 20 to enter the recess 16. In fact the flange 20 is locked or engaged under the tongue 15%, and when the bead is disposed in Fig. 1, it, constitutes glazing means for retaining or setting the glass in engagement with the seatafforded by the provision of the tongue 14. It will be noted that one wall of the bead 18 bears against the face of the glass and holds the edge thereof in contact with its seat. The sheet metal. of the sash rail is overlapped as at 21, it being obvious that it may be overlapped at any location other than that which is shown in Fig. 1.

In Figs. 4 and 5 the sheet metal sash rail preferably has a Wood filler 22, though not necessarily. Also in Figs. 4t and 5 the parallel ears 23 are inserted through the slot 24, and into the tiller, at a point where the filler is mitered, at 25. The ears at this point are provided with openings 26, through which an attaching screw 27 passes. This screw 27 extends on an. angle across the joint of the filler, thereby not only holding the two fillers together, but also acting as means for attaching the ears and securing the sheet metal rails in place. It is obvious that this form. of connection in Figs. 1 and 5 may be used in connection with a wood frame, where the sheet metal casing is dispensed with.

It is also obvious that the form o't sheet metal sash rail in Figs. 1 and 2 may be provided with a filler, it necessary.

The invention having been set forth, what is claimed is:

1. A connector adapted for use in connection with a sash rail, comprising opposed flat plate ears normally in parallelism and adjacent each other, said ears being slotted reversely to form adjacent opposed hooks, whereby upon spreading the ears flatwise from each other and permitting a partial turn to a sash chain link, it may simultaneously engage with both hooks, and means for attaching the ears to the sash rail.

2. A connecter comprising adjacent normally engaging flat plate ears in parallelism, said ears being slotted reversely to form adjacent opposed hooks adjacent certain end portions of the ears, the other end portions ot the ears adapted for passing through a slot in a sash rail, the ntremities ot the ears beyond the sash wall being bent laterally, thereby attaching the ears rigidly to the rail.

3. A connecter with means for attaching the same to a sash rail, said connecter comprising opposed spring plate ears flatwise engaging, certain ends of the ears being slotted reversely to form adjacent opposed hooks, flatwise spreading the ears, and a partial turn of a sash chain link permits engaging the links with the hooks.

4. A connecter comprising opposed flat spring plate ears normally flatwise engaging, certain ends of the ears being engageable through a slot in a sash rail wall, the extremities of the ears beyond the slot being bent laterally parallel with said wall, thereby attaching the ears to the rail, the other ends of the ears having registering openings and provided with slots inclined in opposite directions toward the rail wall and merging into the openings, thereby causing hooks to be formed on the ears, whereby upon springing the ears flatwise from each other and permitting a partial turn of a sash chain link, the latter may simultaneously engage with both ears.

In witness whereof, the inventors signature is hereunto affixed.
